Quote from the knowledge base article Fusion PCBA Specification:
“The lead time for PCB Assembly orders is around 7-15 business days if all the parts are from the Seeed’s OPL and around 20-25 business days if not.”
Furthermore, in the flow-chart “components purchasing” is estimated at
15-20 business days: [attachment=0]PCBA Specification.png[/attachment]
Wow, that’s long! If I order parts via Digi-Key from the US to Germany where I live, then I reliably have them in less than 48 hours. In Shenzhen, I assume that there are plenty of vendors that can get standard parts to the Seeed Studio assembly line the same day.
Can someone explain why making boards is estimated to take about three times as long when non-OPL parts are used? Is there time needed to program machines for non-OPL parts? Does Seeed want to promote OPL parts?
In my case, I need a PCBA in less than four weeks, though fortunately delivered to Hong Kong. I can compromise on all the parts and change the board design in sometimes ugly ways in order to accomodate for OPL parts. However, there is one component where I just cannot find an alternative in the OPL: an ADXL335/337 accelerometer (analog readout, ≤±3G)
